TECHNICAL FIELD

The present disclosure relates to the field of smart gas, and in particular to a method for smart gas pipeline frost heave safety management and an Internet of Things system.

BACKGROUND

When transporting gas to downstream users, with the continuous change of gas supply pressure and flow rate, the pressure before and after pressure regulation is quite different. Due to Joule-Thomson effect, the temperature of distributed gas is easy to drop below freezing point, and the soil around the pipeline freezes, resulting in the “frost heave” phenomenon. That is, the valve body leaves the valve seat, the ground cracks, the pipeline deforms, and local stress concentration occurs, etc., which affects the safe transportation of gas pipeline.

Therefore, it is needed to provide a method for smart gas pipeline frost heave safety management, which can predict the phenomenon of frost heave in advance and take preventive measures in time to avoid the increase of pipeline risk.

It may be understood that after understanding the principle of the system, those skilled in the art may arbitrarily combine each module or form a sub-system to connect with other modules without departing from this principle. In some embodiments, the smart gas user platform and the smart gas service platform disclosed in FIG. 1 may be different platforms in one system, or one platform may realize the functions of the above-mentioned two or more platforms.

FIG. 2 is an exemplary flowchart illustrating a process of a method for smart gas pipeline frost heave safety management according to some embodiments of the present disclosure. As shown in FIG. 2 , process 200 includes the following steps. In some embodiments, process 200 can be executed by the Internet of Things system for smart gas pipeline frost heave safety management.

Step 210, obtaining gas transmission data and gas pipeline data, and determining gas pressure change data of a target point based on the gas transmission data and the gas pipeline data.

Gas transmission data refers to data related to gas transmission. For example, the gas transmission data may include gas flow, gas flow velocity, gas pressure at different positions, gas temperature, or the like. The gas flow refers to the amount of gas fluid flowing through the effective section of the gas pipeline per unit time. The gas flow velocity refers to the distance that the gas passes in unit time. The gas pressure refers to the force between the gas and the inner wall of the gas pipeline. The gas temperature indicates degree of heating or cooling of the gas.

In some embodiments, gas transmission data may be obtained by a plurality of gas transmission sensors. For example, the gas transmission data may be monitored and obtained by the gas transmission sensors of the smart gas pipeline network equipment object sub-platform. In some embodiments, the gas transmission sensor of the smart gas pipeline network equipment object sub-platform receives the instruction for obtaining gas transmission data sent by the smart gas pipeline network equipment sensor network sub-platform and uploads the gas transmission data to the corresponding smart gas pipeline network equipment sensor network sub-platform.

Gas pipeline data refers to data related to pipelines for transmitting gas. For example, the gas pipeline data may include pipeline material, pipeline diameter, pipeline buried depth, pipeline valve quantity, pipeline position, etc.

In some embodiments, gas pipeline data may be obtained by a plurality of gas pipeline sensors. For example, the gas pipeline data may be monitored and obtained by the gas pipeline sensor of the smart gas pipeline network maintenance engineering sub-platform, and sent to the smart gas pipeline network maintenance engineering sensor network sub-platform. In some embodiments, gas pipeline data may also be obtained based on the smart gas pipeline network risk assessment management sub-platform. For example, the gas pipeline data of each pipeline may be obtained based on the pipeline network basic data management module.

The target point is the position in the pipeline that needs to be monitored for safety problems. Safety problems may at least include frost heave of pipelines, gas leakage, etc. For example, the gas pressure in the pipeline may change when the pipeline has frost heave or gas leakage, so the target point may include the position where the gas pressure in the pipeline changes. The number of target points may be one or more, which may be determined according to the actual monitoring situation of the gas pipeline.

The gas pressure change data is data characterizing the degree of change of the gas pressure of the target point. For example, the initial pressure of the target point (that is, the pressure at the beginning of pressure monitoring) is 2.5 Mpa, and the pressure change data of the target point at a certain time point may be 0.2 MPa lower than the initial pressure of the target point, 0.4 MPa higher than the initial pressure of the target point, etc. In some embodiments, the gas pressure change data may include pressure change data at multiple time points. For example, (0.2, 0.5, 0.8, 1.5) may represent that the degree of change of the four consecutive time points relative to the initial pressure is 0.2 MPa, 0.5 MPa, 0.8 MPa, 1.5 MPa.

In some embodiments, the gas pressure change data may be determined based on various methods. For example, the gas pressure change data may be determined based on the temperature model, that is, feature extraction is performed on the gas transmission data and gas pipeline data, and the extracted feature is input into the trained temperature model to obtain the gas pressure change data. For more information about the temperature model, please refer to the related description in FIG. 3 .

In some embodiments, the gas pressure change data may also be determined based on simulation or emulation. For example, the gas transmission data and the gas pipeline data are input into the computer model for simulating or emulating the pipeline environment to obtain the gas pressure change data.

In some embodiments, the gas pressure change data may also be obtained based on the smart gas pipeline network object platform. For example, the smart gas pipeline network equipment object sub-platform receives the instruction for obtaining gas pressure change data sent by the smart gas pipeline network equipment sensor network sub-platform and uploads the gas pressure change data to the corresponding smart gas pipeline network equipment sensor network sub-platform.

Step 220, predicting a temperature change data of the target point based on the gas pressure change data.

The temperature change data is data characterizing the temperature change degree at the target point or near the target point. For example, the initial temperature of the target point (i.e., the temperature at the beginning of temperature monitoring) is −10° C., and the temperature change data of the target point at a certain time point may be: 2° C. lower than the initial temperature of the target point, 4° C. higher than the initial temperature of the target point, etc. In some embodiments, the temperature change data may include the temperature change degrees of multiple time points, for example, (−3, −5, −8, −15) may indicate that the change degrees of four consecutive time points relative to the initial temperature are −3° C., −5° C., −8° C., and −15° C. respectively.

In some embodiments, the temperature change data may include gas temperature change data and soil temperature change data. For more information about the gas temperature change data and soil temperature change data, please refer to the related descriptions of FIG. 3 .

In some embodiments, the smart gas pipeline network safety management platform may predict the temperature change data of the target point based on the gas pressure change data. For example, the smart gas pipeline network safety management platform may establish the gas pressure-gas temperature relationship curve of the target point based on historical data, and predict the temperature change data of the target point based on the relationship curve. For another example, the smart gas pipeline network safety management platform may predict the temperature change data of the target point based on the model.

In some embodiments, the smart gas pipeline network safety management platform may predict the temperature change data of the target point through the temperature model based on the gas transmission data and the gas pipeline data. For more information about the temperature model, please refer to the relevant descriptions of FIG. 3 .

Step 230, predicting, based on temperature change data, gas pipeline data, and gas pressure change data, and in combination with environmental data, a frost heave degree data of the target point.

Environmental data refers to the relevant data of the environment where the target point is located. For example, the environmental data of the target point may include the environmental temperature, weather, soil water content, soil type, etc.

In some embodiments, environmental data may be obtained by a plurality of environmental sensors. For example, the environment may be monitored and obtained by the environmental sensors of the smart gas pipeline network equipment object sub-platform. In some embodiments, the smart gas pipeline network equipment object sub-platform receives the instruction for obtaining environmental data sent by the smart gas pipeline network equipment sensor network sub-platform and uploads the environmental data to the corresponding smart gas pipeline network equipment sensor network sub-platform.

Frost heave degree data is the data characterizing the severity of frost heave at the target point. For example, frost heave degree data may include frost heave range and frost heave severity. The frost heave range may include the length and depth of the frost heave, and the frost heave severity may include whether it causes surface uplift or pipeline deformation and damage.

In some embodiments, the smart gas pipeline network safety management platform may predict the frost heave degree data of the target point. For example, the smart gas pipeline network safety management platform may build a vector database based on the gas pipeline data and historical data of the target point (for example, historical temperature change data, historical gas pressure change data, historical environmental data, historical frost heave degree data, etc.), and predict the frost heave degree data of the target point based on vector matching. For another example, the smart gas pipeline network safety management platform may predict the frost heave degree data of the target point based on the model. For more information about predicting frost heave data of target points based on the model, please refer to the related descriptions of FIG. 4 .

In some embodiments, the smart gas pipeline network safety management platform may determine the initial frost heave range based on gas transmission data, gas pipeline data, and gas temperature change data, adjust the initial frost heave range based on environmental data, and determine the frost heave degree data of the target point.

The gas temperature change data is data characterizing the change degree of the gas temperature of the target point. For example, the initial gas temperature of the target point (i.e., the gas temperature before pressure regulation) is −15° C., and the gas temperature change data of the target point at a certain time point may be: 3° C. lower than the initial gas temperature of the target point, 5° C. higher than the initial gas temperature of the target point, etc. In some embodiments, the gas temperature change data may include the gas temperature change degrees at multiple time points, for example, (−2, −4, −8, −12) may indicate that the gas temperature change degrees at four consecutive time points are −2° C., −4° C., −8° C., and −12° C., respectively.

The initial frost heave range refers to the data preliminarily determined to characterize the frost heave severity according to the gas transmission data, gas pipeline data, and gas temperature change data. For example, the initial frost heave range may include frost heave length, frost heave depth, or the like.

In some embodiments, the smart gas pipeline network safety management platform may determine the initial frost heave range based on gas transmission data, gas pipeline data, and gas temperature change data. For example, the smart gas network safety management platform may build a vector database based on the gas pipeline data and historical data of the target point (for example, historical gas temperature change data, historical gas transportation data, historical initial frost heave range, etc.), and determine the initial frost heave range based on vector matching. For another example, the smart gas pipeline network safety management platform may predict the initial frost heave range of the target point based on the model.

In some embodiments, the smart gas pipeline network safety management platform may adjust the initial frost heave range based on the environmental data and determine the frost heave degree data. For example, it may be determined whether the frost heave causes surface uplift or pipeline deformation and damage according to the soil type, the initial frost heave range is adjusted, so as to determine the actual frost heave degree data. If the soil is hard, the surface deformation degree is relatively low, and the corresponding frost heave degree is relatively light. For another example, possible differences of frost heave degrees under different temperatures and/or different weathers may be determined according to ambient temperature and/or weather, so as to more accurately determine frost heave degree data.

In some embodiments, the smart gas pipeline network safety management platform may determine the frost heave degree data based on the frost heave model. For more details about the frost heave model, please refer to the related descriptions of FIG. 4 .

Step 240, determining, based on the frost heave degree data of the target point, the gas transmission adjustment data and a frost heave prevention plan.

Gas transmission adjustment data refers to related data used to adjust the gas transmission data. For example, the gas transmission adjustment data may include adjusted gas flow and gas pressure.

In some embodiments, the gas transmission adjustment data may be determined based on various methods. For example, the smart gas pipeline network safety management platform may first adjust the gas transmission data based on the target point with the most severe frost heave and then determine the gas transmission adjustment data. For example, a table of historical frost heave degree data-historical gas transmission adjustment data may be established based on the historical management data of gas pipelines, and the frost heave degree data may be input into the table for matching, and the matched historical gas transmission adjustment data may be determined as gas transmission adjustment data.

The frost heave prevention plan refers to the solution used to prevent frost heave at the target point. For example, the frost heave prevention plan may include a plurality of treatment ranges and treatment methods, and different frost heave ranges and different frost heave severities correspond to different treatment ranges and treatment methods. The treatment methods may include soil replacement, adding an isolation layer/insulation layer/insulation layer, waterproof treatment, artificial heating measures, etc.

In some embodiments, the smart gas pipeline network safety management platform may establish a vector database based on environmental data and historical data (for example, historical gas transmission data, historical temperature change data, historical frost heave prevention plan, etc.), and determine the frost heave prevention plan by vector matching. For example, if the soil has a high moisture content, the frost heave prevention plan may include waterproofing. If the soil is prone to frost heave, the frost heave prevention plan may include replacing with other types of soil.

In some embodiments, the smart gas pipeline network safety management platform may determine the gas transportation adjustment data based on the frost heave degree data of the target point, determine the temperature change update data through a temperature model based on the gas transportation adjustment data, determine the frost heave degree update data based on the adjusted temperature change data through the frost heave model, and determine the frost heave prevention plan based on the frost heave degree update data. For more information about determining the frost heave prevention plan, please refer to the related descriptions of FIG. 5 .

The method for smart gas pipeline frost heave safety management in some embodiments of the present disclosure realizes the effective adjustment of gas transmission by predicting the frost heave degree data of the target point and determining the gas transmission adjustment data and frost heave prevention plan, thereby effectively avoiding frost heave of the gas pipelines.

It should be noted that the above description of process 200 is only for example and explanation, and does not limit the scope of application of this disclosure. For those skilled in the art, various modifications and changes may be made to the process 200 under the guidance of the present disclosure. However, such modifications and changes are still within the scope of the present disclosure.

FIG. 3 is a schematic diagram of a temperature model according to some embodiments of the present disclosure. As shown in FIG. 3 , process 300 of executing and training of the temperature model at least includes the following contents.

In some embodiments, the smart gas pipeline network risk assessment management sub-platform may predict the temperature change data of the target point through a temperature model at least based on the gas pressure change data. The temperature model may be a machine learning model.

The temperature model 330 is a model for predicting temperature change data of a target point. In some embodiments, the temperature model may include a convolutional neural network model or a deep neural network model.

In some embodiments, the input of temperature model 330 may include gas transmission data 310 and gas pipeline data 320. For more information about gas transmission data and gas pipeline data, please refer to the related descriptions of FIG. 2 .

In some embodiments, the output of the temperature model 330 may include gas temperature change data and soil temperature change data.

The gas temperature change data is usually the data characterizing the degree of gas temperature change at the target point. For example, the gas temperature change data may include the temperature change data of the gas in the pipeline at a plurality of time points compared with the initial gas temperature of the target point.

The gas temperature change data may be represented by a vector, and different elements in the vector represent the change data of the gas temperature at different time points. For example, if the initial gas temperature is 15° C., the gas temperature is 12° C. after 1 hour, 9° C. after 2 hours, 6° C. after 3 hours, 3° C. after 4 hours, etc., then the gas temperature change data may be expressed as (−3, −6, −9, −12), which may indicate that the decrease ranges of temperature at four consecutive time points are −3° C., −6° C., −9° C., and −12° C., respectively. The time point may be manually set (such as 10 minutes, or half an hour, etc.), and the time point may also be set as multiple (such as 6). That is, when the time point is set as half an hour and the number of time point is 6, the gas temperature change data may be expressed as (−1.5, −3, −4.5, −6, −7.5, −9), indicating that the gas temperature drops by −1.5° C. every half hour compared with the initial gas temperature. It can be understood that the gas temperature change data may also be expressed in other ways.

The soil temperature change data is usually the data characterizing the soil temperature change around the target point. For example, the soil temperature change data may include the temperature change data of the soil around the gas pipeline network at a plurality of time points compared with the initial soil temperature.

Similar to the gas temperature change data, the soil temperature change data may also be expressed by vector, and different elements in the vector represent the gas temperature change data at different time points.

FIG. 5 is a schematic diagram of determining a frost heave prevention plan according to some embodiments of the present disclosure. As shown in FIG. 5 , process 500 includes the following steps. In some embodiments, process 500 may be executed by the smart gas pipeline network risk assessment management sub-platform.

Step 510, determining, based on the frost heave degree data of the target point, the gas transmission adjustment data.

In some embodiments, the smart gas pipeline network risk assessment management sub-platform may determine the gas transmission adjustment data based on the frost heave degree data of the target point. For more description about determining, based on the frost heave degree data of the target point, the gas transmission adjustment data, refer to the relevant descriptions of step 240 in FIG. 2 .

Step 520, determining temperature change update data through a temperature model based on the gas transportation adjustment data, and determining frost heave degree update data through a frost heave model based on the temperature change update data.

The temperature change update data may refer to updated temperature change data based on the gas transmission adjustment data. In some embodiments, the temperature change update data may include gas temperature change update data and soil temperature change update data. The gas temperature change update data refers to new gas temperature change data when the gas transmission is performed based on the gas transmission adjustment data. Similar to the gas temperature change data, the gas temperature change update data may include the update data of the gas temperature change degree at a plurality of time points, for example, (−1, −2, −2.5, −3) may represent the gas temperature change degrees at four consecutive time points relative to the initial temperature are −1° C., −2° C., −2.5° C., and −3° C., respectively after adjusting gas transmission data. The soil temperature change update data refers to the new soil temperature change data when gas transmission is performed based on the gas transmission adjustment data. Similar to the soil temperature change data, the soil temperature change data may include the soil temperature change degrees at multiple time points. For example, (−2, −3, −5, −8) may indicate that the soil temperature change degrees at four consecutive time points relative to the initial temperature are −2° C., −3° C., −5° C., and −8° C., respectively after adjusting the gas transmission data.

In some embodiments, temperature change update data (i.e., gas temperature change update data and soil temperature change update data) may be obtained based on gas transmission adjustment data, gas pipeline data, and environmental data through a temperature model. In some embodiments, the foregoing temperature model may be a machine learning model, specifically, which may be the temperature model 330 in FIG. 3 of the present disclosure. For example, gas transportation adjustment data and gas pipeline data are input into the temperature model 330, and updated gas pressure change data is obtained through the gas feature extraction layer 331. The updated gas pressure change data and gas transmission adjustment data are input into the first temperature layer to obtain the gas temperature change update data. The gas temperature change update data and environmental data are input into the second temperature layer to obtain soil temperature change update data.

The frost heave degree update data refers to the frost heave degree data re-predicted based on the gas transmission adjustment data and the soil temperature change update data. The frost heave degree update data may include an updated frost heave range and an updated frost heave severity. The frost heave range may include the length and depth of the frost heave, and the frost heave severity may include whether it causes surface uplift or pipeline deformation and damage. The frost heave degree update data may be represented by vectors, for example, (1, 0.2, 0, 1) may represent a frost heave degree update data, the first element in the vector indicates that the frost heave length is 1 m, the second element in the vector indicates that the frost heave depth is 0.2 m, the third element in the vector and the fourth element in the vector respectively indicate whether there is surface uplift and pipeline deformation, and 1 indicates that there is surface uplift and pipeline deformation, and 0 indicates that there is no surface uplift and pipeline deformation. That is, in the above frost heave degree update data, it is indicated that there is no surface uplift and pipeline deformation at the target point. The frost heave degree update data may also be expressed in other ways or include other data that may reflect the frost heave degree, which may be determined according to actual needs.

In some embodiments, the frost heave degree update data may be obtained through a frost heave model based on the gas transmission adjustment data, soil temperature change update data, gas pipeline data, and environmental data. In some embodiments, the foregoing frost heave model may be a machine learning model, specifically, which may be the frost heave model 410 in FIG. 4 of the present disclosure. For example, the gas transmission adjustment data, gas pipeline data, and soil temperature change update data are input into the frost heave model 410, the initial frost heave range is obtained through the processing layer 411, and the initial frost heave range and environmental data are input into the prediction layer to obtain the frost heave degree update data.

Step 530, determining, based on the frost heave degree update data, a frost heave prevention plan.

In some embodiments, the smart gas pipeline network risk assessment management sub-platform may determine the frost heave degree update data based on the gas transmission adjustment data, and determine the frost heave prevention plan corresponding to the adjusted gas transmission data according to the frost heave degree update data.

Frost heave prevention plan includes treatment range and treatment method. According to the updated frost heave range and the updated frost heave severity in the frost heave degree update data, different frost heave ranges and different frost heave severity correspond to different treatment ranges and treatment methods. For example, the frost heave range is a length range of 500 m along the front and back of the gas pipeline with the target point as the midpoint, and a range less than or equal to 1 m from the outer surface of the gas pipeline, the treatment range in the frost heave prevention plan is a length range of 500 m along the front and back of the gas pipeline with the target point as the midpoint and a range less than or equal to 1 m from the outer surface of the gas pipeline. For another example, if the frost heave severity is severe (causing surface uplift or pipeline deformation and damage, etc.), then treatment method is taken to avoid frost heave in the soil. Treatment method to avoid frost heave in soil may include soil replacement, adding an isolation layer, thermal insulation layer, and insulation layer on the periphery of the gas pipeline at the target point, waterproofing treatment of the soil (e.g., covering the soil surface with a tarp to prevent rainwater penetration), implementing artificial heating measures, etc. For the specific content of the frost heave prevention plan, refer to its related descriptions of FIG. 2 .

In some embodiments, a historical database may be established based on historical frost heave treatment data, and a frost heave prevention plan may be determined by means of vector matching. For example, a comparative analysis is made to determine the frost heave prevention plan based on the current frost heave degree update data and the historical frost heave degree update data. In some embodiments, vectors Ai (i=1, 2, 3, . . . , n) may be constructed based on historical frost heave degree update data, where i is the number of historical frost heave degree update data, and each vector Ai corresponds to a historical frost heave prevention plan to form a historical database. The historical frost heave degree update data may be data representing different frost heave ranges and different frost heave severity. Environmental data may be considered when building a historical database. For example, vector elements may include (the length of the frost heave range, depth of the frost heave range, degree of surface uplift, degree of pipeline deformation, and soil moisture content).

As an example only, when the vector is (500, 1, 1, 1, 10), it means that in the historical frost heave degree update data, the frost heave range is a length range of 500 m along the front and back of the gas pipeline with the target point as the midpoint, and the range less than or equal to 1 m from the outer surface of the gas pipeline. If the surface uplift degree is level 1, the pipeline deformation degree is level 1, and the soil moisture content is 10%, the corresponding frost heave prevention plan is (500, 1, A), which means that the treatment range in the frost heave prevention plan is a length range of 500 m along the front and back of the gas pipeline with the target point as the midpoint, and a range less than or equal to 1 m from the outer surface of the gas pipeline, and the treatment method A is adopted, the treatment method A is to add an insulation layer around the target point pipeline.

The current frost heave degree update data is used to construct a vector B with the same format, and the vector B is matched with the vector Ai in the historical database. For example, the vector distance between vector B and Ai is calculated, and the vector Ai whose vector distance from vector B is smaller than the distance threshold as a matching vector, then the historical frost heave treatment plan corresponding to vector Ai is used as the frost heave prevention plan for the current frost heave degree update data. The vector distance may include various types, for example, Euclidean distance, cosine distance, Markov distance, Chebyshev distance, Manhattan distance, or the like.

The historical frost heave degree update data and the historical frost heave prevention plan are used to establish a historical database, which may quickly determine the frost heave prevention plan corresponding to the current frost heave degree update data, and considering environmental factors when establishing the historical database can make the historical database more in line with the actual situation.

In some embodiments, the non-transitory computer-readable storage medium may store computer instructions, and when the computer reads the computer instructions in the storage medium, the computer executes the method for gas pipeline frost heave safety management.
